 The Jobs panel shows you the number of currently running jobs. Jobs are tasks that run in a separate process, they include converting ebooks and talking to your reader device. You can click on the jobs panel to access the list of jobs. Once a job has completed, by double-clicking it in the list, you can see a detailed log from that job. This is useful to debug jobs that may not have completed successfully.
 
+Keyboard Shortcuts
+---------------------
+
+Calibre has several keyboard shortcuts to save you time and mouse movement. These shortcuts are active in the book list view (when you're not editing the details of a particular book), and most of them affect the title you have selected. The |app| e-book viewer has its own shortcuts, which can be customised by clicking the Preferences button in the viewer.
+
+.. note::
+
+    Note: The Calibre keyboard shortcuts do not require a modifier key (Command, Option, Control etc.), unless specifically noted. You only need to press the letter key, e.g. E to edit.
